Some of\\nthese models are already deployed [52], so we believe the impact of RLHF deserves further scrutiny. Second,\\nprevious work shows that the amount of RLHF training can signi\ufb01cantly change metrics on a wide range of\\npersonality, political preference, and harm evaluations for a given model size [41]. As a result, it is important\\nto control for the amount of RLHF training in the analysis of our experiments.\\n3.2 Experiments\\n3.2.1 Overview\\nWe test the effect of natural language instructions on two related but distinct moral phenomena: stereotyping\\nand discrimination. Stereotyping involves the use of generalizations about groups in ways that are often\\nharmful or undesirable.4To measure stereotyping, we use two well-known stereotyping benchmarks, BBQ\\n[40] (\u00a73.2.2) and Windogender [49] (\u00a73.2.3). For discrimination, we focus on whether models make disparate\\ndecisions about individuals based on protected characteristics that should have no relevance to the outcome.5\\nTo measure discrimination, we construct a new benchmark to test for the impact of race in a law school course',\n",

We\\nfound that RLHF models have a more positive sentiment towards all racial and religious groups, which seems\\npromising, but does not necessarily indicate that biases have been reduced.
